cocoa: fix color profile retrieval

when the color profile was changed it used the right NSScreen but with
the old colorSpace. this was optimised out by a previous commit because
of a wrong assumption. we need to update the screen so we can get the
new colorSpace. this adds a bit of redundancy since on screen change it
will update screen pointer twice.
